Casio Protrek PRW -3000 Tough Solar. Radio wave solar compatible with 6 stations in the world (2 x Japan, North America, UK, Germany, China). Triple sensor that can measure bearing, altitude, air pressure, and temperature. When a characteristic change in air pressure occurs, an arrow and an alarm sound are used to indicate the air pressure trend information alarm. Low temperature resistant specification (-10 °C). It's a one-of-a-kind used item, so I can't recommend it to people who want the quality of a new one.
Check it out in the photo.
It is also used, so if you- are nervous, please refrain from it.
